Reward chemical must decay rapidly, this longer lasting chemical is generated during that decay. Useful chemical to monitor in the Science Kit to see if reward has occurred. Biochemical use as a measure of 'recent' reward.

55 Punish Echo 37

Punishment chemical must decay rapidly, this longer lasting chemical is generated during that decay. Useful chemical to monitor in the Science Kit to see if punishment has occurred. Biochemical use as a measure of 'recent' punishment.

Decays over time, switching on receptors to change the stage of life from embryo through to senile. Stage changes then switch on new genes.

57 Starch 39

Emitted by food objects - converts to Glucose for energy. Does NOT decrease hunger in pre-Life Kit norns - this is done directly by Hunger-- (saccharin), so that junk food can contain high saccharin levels but low starch, etc.

58 Glucose 3A

Produced from starch and in a reversible reaction from glycogen. Used up by muscle action.

59 Glycogen 3B

Life force. Long-term energy reserve, produced in reversible reaction from glucose. Produces Glucose to replenish supplies for muscle action. Absence of Glycogen is life threatening.
